Hi,

i just want to pass in an expression value for my different servers in domain mode for the messaging attribute "backup-group-name". I define it in one of my slave hosts like this:

<server name="my-server" group="my-server-group" >
<system-properties>
    <property name="jboss.messaging.hornetq.backupgroup" value="myvalue"/>
</system-properties>
</server>

and reference it in my domain.xml of my domain controller like this:

<hornetq-server>
...
<backup-group-name>${jboss.messaging.hornetq.backupgroup}</backup-group-name>
...
</hornetq-server>

I see that this value is set when my server starts:

....
jboss.messaging.hornetq.backupgroup = myvalue
...

Now i just wanted to evaluate whether the expression is correctly resolved in cli, but i can't get it right. For a start, i tried to use resolve it with the following command:

/:resolve-expression-on-domain(expression=${jboss.messaging.hornetq.backupgroup})

but then i just get the following result:

{
    "outcome" => "success",
    "result" => undefined,
    "server-groups" => {
        "main-server-group" => {"host" => {"master" => {"server-one" => {"response" => {
            "outcome" => "success",
            "result" => "$"
        }}}}},
        "my-server-group" => {"host" => {"my-host-controller" => {"my-server" => {"response" => {
            "outcome" => "success",
            "result" => "$"
        }}}}}
    }
}

But the expression should be supported here, as far as i see from executing /profile=full-ha/subsystem=messaging/hornetq-server=default/:read-resource-description:

"backup-group-name" => {
    "type" => STRING,
    "description" => "Der Name eines Satzes von live/backups, die miteinander replizieren sollten",
    "expressions-allowed" => true,
    "nillable" => true,
    "min-length" => 1L,
    "max-length" => 2147483647L,
    "access-type" => "read-write",
    "storage" => "configuration",
    "restart-required" => "all-services"
}

So i just don't get it: how can i show the resolved value, or am i still doing sth. wrong? Isn't there a way to resolve the expression directly on my messaging node on the concrete server? (because when i try to get the values there, i just get the expression itself...)
